92 Camaro with major electrical problems

My 92 Camaro is a sweet old thing less than 100,000 miles and has been great. I have spent some money on starting to get it up to scratch. New alternator, starter motor, fuel pump, struts and shocks, was happy and didnt mind as I did most of the work myself. Mechanics are far more important to me than looks.

Now she's letting me down big time. After finding a wet spot on the carpet I didnt know where it came from. The electrics seem to be failing progressively. In 24 hours it has gone from fine to the following not functioning. 1/. the knock sensor, 2/. the starter motor 3/. the fuel pump, et al. Now I realise there may have been some way for fluid to get in the back of the dashboard even though I have driven this car in driving rain with no leaks and the coolant isn't down. Are these systems on the same part of the wiring? I found a dead short in the wire to the starter I dont know where it was shorted as nothing showed but butchering a patch means it will turn over at least.

MAYDAY!!!!!

See if the fluid you mention feels "oily" If it is, you have a bad heater core. What is even worse is that radiator fluid conducts which will make a mess of your electrical system. One more thing, you have 2 computers in the dash on the passenger side. If those got it, you'll need to completely clean the wiring and computers with a mild detergent.

Thanks for replying! The fluid doesn't feel oily and there doesn't seem to have been a drop in the coolant levels. There does however seem to be no A/C any more which makes me think it is what blew out somehow.

I was a little suspect of it when the weather warmed up and the Air didn't get real cold. I know the evaporator is in a sorry state but found one for $90 delivered brand new. Guess I am gonna have to dissassemble the dash maybe.

I was trying to avoid it if possible! Further work with a multimeter and some side cutters has revealed the problem is between the bear stick and the firewall I think. the interlock switch thing doesnt seem to work at all and it was working perfectly the day befoe everything went to hell on a hand cart. Further suggestions welcome!!!!!!!!

it is your wire harness at the fire wall that is shorting out the ground. Fix it now or it will keep getting worse.
